Knee-Related Function and Psychological Aspects After ACL Reconstruction Among Individuals With and Without...

Area of Science:

• Orthopedics
• Sports Medicine
• Psychology

Background:

• Kinesiophobia, or fear of movement, is linked to poor return-to-sport rates after anterior cruciate ligament reconstruction (ACLR).
• Understanding patient perspectives on rehabilitation is vital for optimizing recovery.
• Psychological factors significantly influence outcomes following ACLR.

Purpose of the Study:

• To explore and compare the rehabilitation and recovery experiences of ACLR patients with high versus low kinesiophobia.
• To analyze activity levels, functional status, and psychological well-being in relation to kinesiophobia severity.
• To identify specific behaviors and coping mechanisms associated with different levels of kinesiophobia post-ACLR.

Main Methods:

• A mixed-methods approach was employed, combining quantitative surveys with qualitative interviews.
• Participants with primary ACLR were categorized into high and low kinesiophobia groups using the Tampa Scale of Kinesiophobia-11.
• Validated outcome measures assessed activity (Tegner, Marx), function (IKDC, KOOS), return to sport readiness, and anxiety (GAD-7).

Main Results:

• Both high and low kinesiophobia groups reported fear of re-injury, activity avoidance, and interlimb asymmetry.
• A significant difference was observed in Knee Injury and Osteoarthritis Outcome Scale (KOOS) quality of life scores, with the high kinesiophobia group scoring lower.
• No significant differences were found in other quantitative outcome measures between the groups.

Conclusions:

• ACLR patients exhibit psychological, biomechanical, and behavioral changes impacting recovery.
• Lower quality of life in high kinesiophobia patients underscores the detrimental effect of movement fear on perceived recovery.
• Integrating psychological assessments into rehabilitation protocols is essential for enhancing ACLR patient outcomes.
